Python / Django: Get var from cookies

How to pass data from one view to the next
Summary: I am trying to build a job site. On index.html the user enters a zip code into a form to see jobs in that zip code, this form is handled with the job_query view.

Django session handling on WebGL?
If you read this https://docs.djangoproject.com/en/dev/topics/http/sessions/ This means that Django handle the session only with cookies. The problem is that my in my WebGL application, the browser itself handles the Cookies. Thus imagine the scenario on Chrome: open 2 tabs on the same WebGL URL, without connecting: they both display the connexion form. Tab A: you log as "Olivier". You get the set-cookie from Django "xaC2x..blabla". Chrome stores it in its "global" storage Tab B: you log as "Reivilo". Django gets the cookie "xaC2x..blabla", disconnects "Olivier", an connects "Reivilo" Tab A: from this point, whatever you will do on Tab A will be sent as "Reivilo" because "Reivilo" is connected with the cookie "xaC2x..blabla". So all in all, what you be your suggestion to handle this problem with Django? I could do very complex URL rewriting if needed, I'm just looking for a simple and easy to handle in Django (even if I do very complex URL rewriting in nginx) solution. -
Django Combine two templated from different apps
I have two apps with the following structure project-> main app-> templates-> dashboard.html my app-> templates-> mydashboard.html I want to include mydashboard into dashboard, well this is possible using include template tag. but my problem appears when I have to pass some parameters into mydashboard, let's say they are named param1 and param2 these parameters are the variables which I have to load from my app app. well one possible method is to filling these params in dashboardview in mainapp and pass them using include tag into mydashboard.html like below def user_dashboard(request): ...-->here I have to get data from my app (this view is in main app and I do not want to make main app be dependent to my app return render(request, 'dashboard.html', {'param1': 0, 'param2': 34}) then in dashboard.html I add this part {% is_app_installed "myapp" as is_myapp_installed %} {% if is_myapp_installed %} {% include "myappdashboard.html" with param1=param1 param2=param2 %} {% endif %} It seems the above method works but the main problem is that using this method mainapp is dependent to myapp and I do not want to this happens. is there any other method to load those param1 and param2 inside myapp? thanks -

select_related on many to many with custom through table
I have two models, Foo and Bar, and I have created a many to many relationship with a custom through table, FooBar. class Foo(models.Model): foofield = models.CharField() class Bar(models.Model): barfield = models.CharField() foos = models.ManyToManyField('Foo', through='FooBar', related_name='foo_bar') class FooBar(models.Model): foo = models.ForeignKey(Foo, related_name='foobar') bar = models.ForeignKey(Bar, related_name='foobar') foobarfield= models.CharField() What I would like to do is display all Bar records for a given instance of Foo, and for each such record also display the corresponding value of foobarfield. So I would get something like barfield_value1, foobarfield_value1 barfield_value2, foobarfield_value2 barfield_value3, foobarfield_value3 ... I can't seem to construct the correct query to do this though. I tried something like Bar.objects.select_related('foobar').filter(foobar_foo = foo_instance) Since I would expect foobar to be unique for a give instance of Foo but this does not seem to work. How do I get the result I want? -
Model creation with Celery
I have a post_save signal which triggers a Celery task. That task have to get a list of clients from a readlonly table and create a record for every item, around 250k items. What is the best practice to deal with this using celery asynchronously? A single task looping all 250k clients @task def client_create(store_id): clients = Clientes.objects.all() for client in clients: Client.objects.create(**ClientSerializer(client).data) or a second task to throw everything into a queue @task def queue_client(store_id): clients = Clientes.objects.all() for client in clients: client_create.delay(ClientSerializer(client).data) @task def client_create(data): Client.objects.create(**data) -
Creating inbox of messages (from Django model)?
I'm trying to design an inbox for user messages. I have the Message model and I'm trying to display the created messages. models.py class Message(models.Model): subject = models.TextField(max_length=1000, blank=True) text = models.TextField(max_length=10000, blank=True) sender = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null = True, related_name="sender" ) receiver = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null = True, related_name="receiver" ) profile.html ## SIDE BAR (COLUMN 1) <div class="tbody"> {% for message in received %} <div class="ui card mcard" onclick="openMessage(--insert--here)"> <div class="content"> <div class="header">{{message.subject}}</div> <div class="text">{{message.text}}</div> </div> </div> {% endfor %} </div> ## COLUMN 2 <div class="ui column"> <div class="row"> <div id="subject"> </div> <div id="firstname"> </div> <div id="lastname"> </div> </div> <div class="row" id="text"> </div> </div> I displayed a list of messages (just subject and sender) in a scrollable side bar. When you click on the card for the specific message, I want all the contents to display in the main (right) column. This is basically how Apple mail works if you know what that looks like. I'm having trouble getting the right column to display the content because I can't pass the Django Message object to the function (because it's basically running a loop to create cards). Is there a relatively easy solution to this? TLDR - basically, … -
Django - Displaying a user list takes over 14 seconds, how to speed it up?
I have a view that will display members based on the letter someone select(ex: clicking L on the webpage will display all the members whose firstname start with L, ordered by lastname) The problem is that it can take over 14 seconds to display the page(like"M", around 180 members to list, 17 seconds or so to do so.) . The SQL query doesn't seems the problem since Debug Toolbar reports that it takes less than a second for the query. Here is the view: def show_all_members(request, letter): members = MyUsers.objects.filter(firstname__istartswith=letter).order_by('lastname') alphabet = list(string.ascii_lowercase) request.session['url'] = request.get_full_path() context_dict = {'all_members': members, 'alphabet': alphabet} return render(request, "users/show_all_members.html", context_dict) Programming is a hobby so I'm a bit lost on what is happening here and how to optimize it. Any help and pointer is appreciated. Using Django 2.1.1 -

Calculate an average value for each month
I try to calculate the average amount for each month for the 13 last month. So I have a card with the date which has many amounts which are linked to a category. For example my card 1 has an amount for category A, an amount for category B an amount for category C .... Amount, Card and Category have their own class in the model. My objective is to calculate for one category, the average amount for each 13 last month.

Polymorphic (derived model referred) model inheritance in Django
I have the following inheritance structure of my Django models: Transaction SimpleTransaction SubscriptionTransaction Item SimpleItem SubscriptionItem The model SimpleTransaction refers to the model SimpleItem and the class SubscriptionTransaction refers to the model SubscriptionItem. The most obvious way to do this is to define item field in Transaction: class Transaction(models.Model): # ... item = models.ForeignKey('Item') # ... But I would like t.item to refer to SimpleItem or SubscriptionItem (not the base class Item as in the above code) dependently on whether t is SimpleTransaction or SubscriptionTransaction. What are the ways to do this in Django? Or maybe referring to a derived class (SimpleItem or SubscriptionItem) instead of Item may somehow impact performance badly, as it would request to read SimpleItem or SubscriptionItem even when just Item fields are needed? and so better to refer to the base class and not to invent a question like this? However having references to a particular Item-derived class (not just Item base class) from either SimpleTransaction or SubscriptionTransaction benefits referential integrity. So should I do this to improve the DB "stability"? -
